METHOD OF PLANING AND TAPERING WOODEN HOOPS.

Specification of Letters Patent No.

To all whom t may cof/wcm:

Be it known that I, CLARK H. BROWN, of Forest Port, in the county ofOneida and State of New York, have invented a new and Improved Machinefor Cutting, Planing, and T apering Strips for the Hoops of Barrels,OheeseBoXes, &c.; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which- Figure1, is a plan or top view of my improvement. Fig. 2, is a detached sideview of the lever and the arm on the carriage by which the rotary planeris adjusted.

Similar letters of reference indicate corresponding parts in the twofigures.

My invention consists in the employment or use of a circular saw and anadjustable or sliding rotary planer operated as will be hereinafterfully shown and described.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, represents a bed or platform on which two parallel ways a, a, areplaced and B, is a carriage which is fitted on said ways, and allowed towork freely back and forth thereon.

O, is a circular saw placed on an arbor D, which has its bearings inuprights b, Z), on the bed A. The saw C, is placed near the inner waya., on the bed.

E, represents a slide which is fitted and works in guides c, on the bedA. This slide is placed at right angles with the ways a., a and itsfront end is connected by an arm cl with a lever F, which is pivoted atabout its center to' the bed A, between the two ways c a.

To the slide E, a vertical rotary planer G, is attached. The planer isfo-rmed of two cutters (l, CZ, attached to a head e, which may besecured to the slide in any proper manner, the head being allowed torotate.

To each end of the lever F, an oblique or beveled projection is placed.These projections are similar to each other, the projection f, being atthe front and the projection f1, at the back end of the lever.

To the inner end of the carriage B, and at one side a pendent g, isattached by a screw h. This pendent may be secured at 16,225, datedDecember 16, 1856.

varying points in the carriage. To the opposite side of the carriage anarm z', is pivoted, shown in both figures.

The operation is as follows :-The bolt, shown in blue, Fig. 1 is got outthe proper length and is placed on the carriage B, the inner end of thebolt being even with the inner end of the carriage. The carriage B, isthen moved along, by any proper feed movement, in the direct-ionindicated by arrow 1. The planer G, as the carriage is thus moved, isquite close to the bolt and consequently makes a deep cut at itscommencement, but the arm z', immediately strikes against the projectionfl, and moves the lever F, and the slide E, and planer G, are graduallythrown back a certain distance. This movement of the planer causes theinner end of the bolt to be cut in taper form; the saw C, now enters thebolt and cuts a strip of the necessary width from it, the planer Grbeing now stationary as regards its lateral or sliding movement, butrotating and planing the side of the bolt which is of course the outerside of the strip when sawed off from the bolt As the outer end of thebolt approaches the planer, and at the proper point, the pendent g,strikes the pro-jection f, on the opposite end of the lever F, and theplaner is moved gradually inward so as to cut the outer end of the boltin taper form.

Thus it will be seen that as each strip is sawed from the bolt its outerside is planed and its ends are cut in taper or beveled form so thatthey may be overlapped to form the lock of the hoop.

The pendent is secured to the carriage at different points according tothe size or diameter of the hoops required, and a scale may be made onthe carriage to serve as a guide in adjusting the pendent. This isimportant, because if the strips vary in length the slide and planermust be moved at t-he proper time in order to insure the ends of thestrips being cut in taper form.

The above machine has been practically tested and operates well. It maybe constructed at a small cost, and much labor is saved by its use. Thesaw and planer may be driven by belts arranged in any proper way.

I do not claim the Circular sa-W and ro- B, Jchrough the medium of thelever F, and 10 tary planer, for they have been previously the pendentg, and arm z', on the carriage B, used for similar or analogouspurposes, but substantially as shown and described for the Having thusdescribed my inventioon, purpose set forth.
